1'0 all whom it wrung concern:

Be it known that I, Siton W. WARDWELL, it citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Winding Com posits (laps, of which thefollowing is a Specification.

This invention relates particularly to the to class of windingenachines, known as quillers or quill-Winders, employed to wind oops or packages for use in loom-shuttles and also to that type of winding-machine designed to wind various materials by the system i5 known to those versed in the art as the V or universal wind.

-My invention consists of means whereby to economically produce a novel composite cop composed of n pl u-relity--two or more-of com- 29 ponent cops, each preferably wound hy the V- wind and all wound from one continuous t end upon one common tube,

Further, my lnvention consists of certain details of construction and appliances, fully 2 5 set forth hereinafter and illustrated in the accompanying drawings, in'Which- Figure l is an end View of one of the innohines, showing the relation of the ports dur- Fig. 2 is a.

The main parts of the machine, which are now well known and familiar to those versed in the art, are the main frame .A,the windingspindle 9", the guide 1,, which is carried by s traverse be! and reciprocetes opposite the spindle and is eisocerried by n pivoted gnidecarrying frame F, weighted to cause the guide to beer on the cop as it is wound, but swing Fig. 28 is a View of the per-ts log back as the cop increases in size, and a.

' detcnt or dog R, Figs. 27 and 28, which per exits the outward swing of the frame F, but

prevents it from swinging heck during the winding operations. vided with e. roll- L0, which enters the groove of the traverse-com D, Fig. 2, and the camshaft is driven from the spindie-sheft by means of suitable appliances, termed the .gainer mechanism, which permit the relation of. the reciprocation of the guide and. rotation oi the spindle to he changed, and

'lhetroversehnrrs prothread passes, one rigid and the other adapted to swing to be pressed against the thread, each with parallel separated fingers, those of one member alternating with those of the other so that the thread passes in a zigzag course between them.

Before describing the machinein detail the principal operations to be mechanically performed thereby will beset forth in ,order that the functions of the various constituent mem- .bers may be more readily comprehended and identified when the latter are explained in detail. To avoidconfusion, the term section will be employed to designate the individ ual masses of thread which together constitute the completed package. The latter will be :termed the f cop, and the device upon which it is wound shall be termed a tube, and by the term tubefi shall be understood a quill, bobbin, spifidle, or any other appropriate device which is or may be employed for such purpose.

In order to Wind such a cop as has been indicated, the following cycle-of events must occur, each. at and only at' its specified appropriate time, each performed mechanically with certainty and'precision. end-of an empty tube a section of predetermined proportions is wound, and when it has attained the desired diameter either the tube on which it is wound or.the traversing guide which deposits each coil of thread. in place must be so shifted that the path of traverse of the threadguide lies entirely beyond the end of the section just finished to wind 3. second section on the unoccupied portion of the tube adjacent the first section; It"

the package is to comprise more/than two sections, this change in the position of the traverse relative to iilfiitlShCOil'lfl leted section must occur at the com pletion of every section but the last, at the completion of which the winding-machine stops.- Different means may be employed to produce the shifting referred to; but preferably an extensible ira-verse-bar is used; adapted to be mechanically elongated after the completion of each section but the last, as above set forth. The shifting mechanism is putinto action mechanically by the swinging of the guide'carrying frame, which for convenience is termed the traverse-frame? When the threac'l-guide hearing on the surface of the cop has swung a distance from the windi ng-spin lie corresponding to the prescribed diameter of the completed -cop, the guide-carrying frame or traverseirame swinging with it is in a llfifjlilbll for certain appropriate devices earrici'l by said traverse frame to be thrown into active connection wbh the operating mechanism of the wind- At one.

eeaase lug-machine to shift the gnidetoa new op erating position and cause the traverse-frame to swing to the spindle. Inasmuch as the thread-guide must necessarily be thrown back from the surface of the cop to piece broken ends or renew exhausted supplies,.and as the winding must sometimes be stopped toperform these operations before a section is completed, there is danger that in swinging the guide away from the package to more readily piece the ends the guide-shifting devices shall be operatively connected with the" machine to shift the traverse as soon as the winding is started,'thus causing a new seclion to be started before the preceding one is completed. To avoid this, the guide-shifting devices are so related to the operating mecli anism that they shall be thrown into active connection therewith only when the latter is in operation. This provision is adequate for the purpose intended, because the thread guide will never be withdrawn from the sur' face of the cop during the winding, except by accident, which of itself would spoil the cop. An essential feature of the various machines employed to produce the V-wind is adetent which allows the I-;read-guide during the Winding of the cop it move only away from the spindle unlessreleased by the operator;

In the improved machine when one section of the cop has been finished and the next of the series is to be started the detent or dog, as it is termed, is released automatically to allow the guide to return to the spindle and then be left free to periorm 'itsfunction as the new section is wound. When the package is completed, the winding is stopped by suitable instrumcntalities constitutinga sizing devi.ce, whose action is influenced bythe diameter oi the final section in the same manner as the action. of the traverse shifting mechanism is influenced by the diameter of the first sectionor sections, this sizingdevice being so arranged that the winding shall stop only when the appropriate section (the last one of the series) has attained the desired diameter. j

The traverse-bar C'slides in the traverseframe F and is sectional or otherwise adapted to be extended mechanically to shift the position of'the traverseof thegnide ism-clatter to the tube as one'after another of; sections that form the comp-let package for main loom-shuttles is fini'she 'lhecops wound in this machine are slightly cohical to better provide for the delivery of the thread. To obtain the desired form of eop, the windingspindle this made ofappropriate taper and'the groove 64: 64, Fig. 17, in the bar 1623 of the lraverse frarne-F, in which the traverse-bar 0 runs, is so inclined to the axis 65 65, on which said traverse-frame swings, that the reciprocating guide i follows the so rt'see of. the winding-spindle 9 to forma cop of corresponding taper. The two sections and 68, Fig. 19, of the traverse bar 0 slide end to end in the groove mentioned, each provided with guides 169, extending into a groove 170 at right angles to the main groove to prevent vertical movement. For convenience the section 68 is designated as the guide-driver and section 67 the guidecarrier. The two are joined by a springcatch 69, one end of which is riveted to the guide-driver 68, while the other has a lug 171 at right angles, adapted to a slot 66 in the guide-carrier 67. At suitable intervals along the guide-carrier other similar slots can be cut, dependent on the number of sections to be included in the cop and consequent number of changes of traverse of the guide. Fig. 19 shows the guide-carrier 67 and the guidedriver 68 closely adjacent, as when the guide is supported in proper position to wind the first section, and Fig. 21 the same parts extended, when the guide is supported in position to wind the last section of the cop. The operation of these parts is asfollows: When the parts are set as in Fig. 19, the first cop is' wound, and when it has attained its full diameter and the guide is at the point of its traverse farthest removed from the frame A the spring-catch 69 is pushed out by devices operating automatically and caused to release the guide carrier 67 which by adequate means is moved longitudinally sufticiently'to carry the thread-guide clear of the end of the completed cop. This adjustment of the guidecarrier is also suiiicient to just bring'the next slot 66 in the guide-carrier into such a position that when the cam has completed a halfrotation and drawn the guide-driver back to its opposite extreme of travel the lug 171 at the extremity of the spring-catch 69 will snap into said slot,thus again connecting the guidedriver to the guide-carrier,- so that the guide is in position to wind the next section of the series opposite another part of the tube. While this extension of the traverse-bar takes place the winding-spindle continues its rotation, so that the thread passes from the periphery of the finished cop-section across the end of the latter and makes several coils about the spindle before the next succeeding copsection is started. This apparently incidental action of the machine is important in winding asectional cop of the character and in the manner for which this machine is designed. Devices may be made whereby the extension of the traverse-bar could be effected without this intermediate winding occurring as it does. Should this be done, a loop would be formed in which the th read-guide would catch on its inward traverse, breaking the thread and destroying the cop. The intermediate winding described causes the thread to be carried upon the completion of one cop-section close beside the end of said completed cop-section to the tube and then by making several turns or coils around the tube sobinds the thread in place that no interfering loop can be formed.

In order to mechanically disconnect the guide-driver 68 from the guide-carrier 67 and change the position of the latter, as just described, a lever H, Figs. 2 and 29, is adapted to rock and slide on a sleeve 7 0, held in bearings 71 and 72 on the frame F, and is provided at the extremity of its arm 101 with an adjustable projection 102. This projection is adapted to be so protruded by the agency of suitable devices through a slot 103 in the frame F as to press the extremity of the springcatch'69 from the slot into which it fits. Adjacent to the rocking lever H on the sleeve is a coiled pressure-spring 104, which tends to force the lever H in the direction of the arrow, Fig. 2, toward the frame A. The lower arm105 of the lever H carries a block 106, adapted to engage with a cam K on the camshaft 25 and in such position that its cycle of action is properly correlated to that of the traverse-cam D. The cam K should operate only when disconnecting and shifting the guide-carrier 67, to which end during the period of winding the cops the block 106 rides inactive on the middle portion of the cam K.-

To minimize the friction and prevent wear on the block and cam, the center of the cam K is provided with a member K, Fig. 24, having a disk 119, which fits a depression in the middle part of the cam protruding slightly above the face of the latter and supported by the small spindle 120. The spindle 120 has a bearing in an axial hole in the cam-shaft, which is fitted with a step 121 for its end. During the period of winding between the times of shifting the traverse of the threadguide the member K remains stationary by contact with the block 106, supporting the latter above the face of the cam, the outer edge of disk 119 being beveled to provide for raising the block 106 when the latter is forced onto it by the action of spring 108. shaft 25 and cam K rotate about the member K, and to further minimize the friction between the spindle 120 and the cam-shaft 25 the middle portion of the spindle is reduced in diameter, leaving bearing-surfaces at the ends only. The disk 119 is free from contact with the cam K.

From the lever H, Figs. 1 and 29, an arm 107 extends laterally and directly beneath va projection 131 of the lever S, making contact therewith at all times during the winding of a cop-section and so posed relative thereto that the movement of the traverse-frameF away from the spindle during the winding shall cause the lever H to be rocked to move the block 106 outward from the axis of the cam K and into operative engagement therewith. To insure that the lever H shall not be rocked by moving the traverse-frame F away from the Windingspindle while the winding is stopped, thus causing an untimely operation of the traverse-extending devices and the results detailed heretofore, the lever S is soconnected with the starting and stopping devices of the machine by means of the arm 133, attached to the shaft 31 and the connect The cam- &

jection 131 is withdrawn from contact with the arm or cam 107 by the rocking of the shaft 31 in the direction of the arrow, Fig. 1. The arm 133 is adjustable on the shaft 31, so that the position of the projection 131 relative to the arm 107 may be varied to effect the engagement' of the block 106 with the cam K when the traverse-frame reaches the distance from the winding-spindle corresponding to the desired diameter of the cop-section being wound.

Fig. 1 indicates the position and relation of the parts at the time of extending the traversebar just following the completion of a copsection. The block 106 has just been operated upon by the second radial rise 123 of the cam K, so that the projection 102 .has just been protruded through the traverse-frame F to disengage the guide-driver from the guidecarrier and to engage with the latter to commence the extension of the traverse-bar. Fig. 29 indicates the position and relation of the parts at the commencement of winding a copsection. When the winding of a cop is to be started, the handle or starting-lever E is rocked to the right into position indicated by the full lines, Figs. 1 and 29, and locked in engagement with the stopping-lever E. The rocking of the handle E, as described, causes, through connections above specified, the lever S to be rocked to throw the projection 131 into contact with the lever-arm 107, which is so inclined to the direction of its own motion with the traverse-frame F, as the latter swings back from the winding-spindle with the increasing diameter of the cop-section -that, bearing against the projection 131, it is depressed. The depression of the arm 107 causes the block 106 to swing outward from the center of the cam K until the prescribed diameter of the cop-section is attained, when the block aforesaid passes from the center portion of the cam K beyond the edge 122 (see Fig. 25) and is forced by the spring 104 into the space in front of the rise 122. The latter sufficiently moves the block 106 to rock the projection 102 into close proximity to the traverse-bar and the spring connection 69. After this movement and after the spring 104k has so far moved the lever H that the block 106 rests against the surface 125 of the cam K the rise 123 engages the block 106 to again rock the lever H to protrude the projection 102 through the traverse-frame F. The projection 102, striking the lug of the springcatch 69, disengages the guide-carrier from the guide-driver, forcing the lug 171 of said spring-catch from the slot 66 in the guidecarrier 67. This disengagement occurs as the traverse-bar O is completing a traverse outward from the machine. The projection 102 in disengaging the spring-catch 69 passes close by the side of the vertical member 181 of the guide-carrier 67. (See Fig. 19.) The block 106 having been moved to its full extent outward from the axis of the cam K by the rise 123 engages the helical rise 125, which causes the lever H to move longitudinally in its bearings'outward from the machine. The projection 102, engaging theedge of the vertical member 181, moves the disengaged guidecarrier 67 also outward from the machine the necessary distance for the thread-guide 2' to clear the completed cop section. In the meantime the cam D is moving the guidedriver 68 to the opposite or inward extreme of its traverse, and the actions of the cam D and the cam K are so correlated that when the guide-driver reaches its inward extreme of traverse the second slot 66 at the inner end of the guide carrier 67 registers with the catch 171, which snaps into said slot, thereby reuniting the guide-driver with theguidecarrier in their extended relation. With the reciprocation of the guide-driver the guidecarrier will now be reciprocated opposite a new and independent portion of the windingspindle to wind a cop-section adjacent to the one just completed. Immediately upon the reconnection of the guide carrier to the guide-driver the latter commences its return or outward traverse, moving the guide-carrier faster than the projection 102, and therefore away fromit. The projection 102 does not complete its movement due to the action of the helical surface 125 of the cam K immediately upon the reconnection of the guidecarrier and guide-holder, but continues its outward movement to effect the shifting of the traverse-frame dog R, as will be later ex* plained, and which must be so timed that it cannot occur before the thread-guide is clear of the completed cop-section.

It is well to note at this point the essential functions and relation of the two separated rises 122 and 123 on the cam K. Then the traverse-bar G is to be extended, the projection 102 must obviously be moved by. the spring 104: a sufficient distance toward the machine to insure that it shall passby the vertical member 181 of the guide-carrier 67 when protruded through the traverse-frame F. \Vere the cam K so constructed that the block 106 could be engaged and operated by the final rise 123 immediately after leaving the edge 122 the projection 102 might be protruded through the traverse-frame F too soon and forced against the guide-holder 1S1 rather than past it, causing damage to the machine. For this reason a first or preliminary rise is provided at 122 and at such a distance from 123 as shall insure the complete movement of the lever II under the action of the spring 104 before the projection 102 can be protruded through the traverseframe F by the action of the rise 123. Should the block 106 complete its outward movement from the axis of the cam K just too late to be engaged by the rise 122, it cannot engage with the rise 123, but must remain in its position until the cam K has sufficiently rotated to permit its proper engagement with the rise 122:

The traverse-frame swings freely outward from the winding-spindle, but is restrained from inward movement by the pinching of an arc Q, pivoted at one end on the stud 73, attached to the main frame between a flattened pin and the dog R, Figs. 27 and 28. The traverse-frame dog is maintained in close contact with the arc Q by the weight of the arm 177 and its connections. Then the traverseframe is pressed toward the winding-spindle, thefriction between the arc Q and the traverseframe dog causes the latter to turn slightly, pinching the arc Q and preventing a movement of the traverse-frame, as described. Vhen the guide has been shifted and is in a position for winding the next section, the dog R must be automatically released that the traverse-frame may be free to carry the guide back to its former position close to the winding-spindle under the influence of weights 61, Figs. 1 and 3, which are attached to a cord connected to the lower arm F of the traverseframe F and carried over a pulley 175, Fig. 3, turning on a stud on the frame A. The employment of this dog,as well as other forms of detent, has been attended with some inconvenience,owing to the fact that with constructionsheretofore employed the operator must use two hands to insure that when the guide has been moved away from the cop it shall be properly returned thereto before again starting the Winding. release the dog and allow the traverse-frame to swing back toward the winding-spindle under the influence of thepressure-weights 61.

Where these weights were but slight, little.

difficulty mightbe experienced; but usually the guide on striking the surface of the package would rebound and remain at a distance from the cop, and the operator without n0- ticing this would start the winding and spoil the package. A natural and almost invariable tendency on the part of inexperienced operators is to replace the traverse-guide against the package by pushing the traverseframe toward it,and failing in this they either go no further and omit the operation or perform it in the manner above outlined, so that it is not effective. To prevent such effects, the dog is moved from a handle 76 at the outer end of a rod 74:, carried by the frame F, and which at the opposite end carries an arm 77, connected with the dog R by means of the link 78 and a pin 79. The position of the handle 76 of the rod 74 is such that the operator places the guide against the package inthe manner that is intuitive-that is, by placing the hand on the handle to push in the frame F-and as the hand remains on the frame there is no rebound and incidental damage to the cop. The pin 79, connecting the arm 77 and the link 78, is provided with a conical head at its outer extremity, Figs. 2 and 28, to engage with a set-screw 110, carried in a projection of the lever H. After the two sections of the traverse-bar have been connected and the guide t'starts outward from the frame A, driven by the cam Operators would frequently.

D, the block 100, still bearing on the rise 125 of the cam K, Fig. 25, continues the movement of the lever H outward from the frame A, thereby bringing the extremity of the screw 110 into engagement with the conical portion of the pin 79, the extremity of said screw having been thrown into line with the conical portion by the first rocking motion of lever H. This conical head of the pin 79 acting as a wedge serves, through the link 78, to lift the weighted arm of the dog R, thereby then releasing the frame F and permitting the frame,with its guided. to be swung toward the winding-spindle under the influence of the weights 61. At the completion'of the above cycle of events the block 106 is at theoutmost point of the rise 1'25, and under the influence of the spring 108, Figs. 22 and 23, acting between the arm 101 of the lever H and a washer 180, bearing on shoulder 190 adjacent to the slot 103 of the frame F, is forced back on the middle portion of cam K, thereby removing the projection 102 from the path of the traverse-bar C and releasing the screw 110 from contact with the pin 79, allowing the dog R to again perform its functions during the winding of the newcop. When the block 106 has been forced back to its normal position at the middle of the cam K, the projection 107 of the lever H, striking against the lower part of the traverse-frame F, prevents excessive movement of the lever H under action of the spring 108.

The lever E carries a long screw 7, upon which the frame F when swung away from the winding-spindle acts to disengage the detents 43 and 46 to stop the winding, as shown in Fig. 1. This screw can be protruded a greater or less distance through the lever E, thus regulating the distance to which the frame F can be swung, and consequently the diameter of the cop at the time the unwind ing thereof isarrested. To coact with this screw there is a sliding blade 80, sliding in a dovetailed groove in 'the frame F, Figs. 18 to 21. At the inner end of the blade opposed to the screw 7 is an opening of sufficient size to pass over the end of the screw without contact, and during the winding of all but the last cop in the package this opening is directly'opposite the end of the screw, as in Figs. 18 and 19, so that the frame F can be swung back without the blade then touching the screw. By this means the machine instead of ceasing work entirely when the first section attains its properdiametersimply ceases work on that section, and by aid of the devices already described automatically transfers the winding operation to the unoccupied portion of the tube beyond the first section. \Vhen,

however, the guide is shifted to wind the last contact with said screw and, pressing against guide-carrier 67 shall pass between it and the traverse-frame F, and the inner end of the projection 81 is in position to contact with a pin 67 on the guide-holder 181, Figs. 18 to 21, to move the slide 80 into such relation to the screw 7 as to stop the winding when the frame F has swung out sufficiently, as above 'set forth. This operation of setting the blade 80'is performed when the guide-carrier makes its first stroke outward in the winding of the last section, and when the cop attains the proper size the blade 80 will make contact with the screw 7 and cause the machine to be stopped. When the composite cop is completed and removed, the guide-carrier must be returned to its initial position. To effect this, the member 81 is provided with a projection 81", which forms a thumb-piece at the outer end of the slide 80 and extends downward to engage a pin 86, which fits a socket in the traverse-frame F. This pin is carried outward by a spring 87, and its movement is limited by a pin 88in the frame F extending into a slot 89 of the pin 86, as shown in Fig. 19. Riveted loosely to the slide 80 is a plate 83, provided with a wedge-shaped lug 84, Fig. 18, formed by bending a part of said plate at right angles and into a recess 85 in the trav erse frame, which recess has its inmost end inclined, rising to the face of said frame, as shown in Figs. 22 and 23. To disconnect the guidecarrier from the guide-driver, the thumb-piece 81 is pressed down, and first the projection 81 is raised to a position to avoid contact with the pin 67 if the guide-carrier 67 happens to remain at or near the end of its traverse when the machine has ceased wind-.

ing. Continued pressure brings the thumbpiece 81 against the end of the blade 80 and forces said blade toward the frame A, and the lug 84 of the plate 83, riding on the inclined end of the recess 85, forces the lower edge of said plate outward, Fig. 23, against the projection of the spring-catch 69, thereby releasing its lug 171 from the slot 66 in whatever position of traverse it may be. This allows the guide-carrier 67 to be moved back to receive the extremity 171 of spring-catch 69 in the appropriate slot for winding the first cop. The upward movement of the projection 81 is limited by a pin 82 on blade 80, and the pin 86, actuated by the spring 87, Fig. 19, and bearing against the lower part of said projection, forces said projection upward and bearing thereon moves the blade 80 back from the position to which it has been pressed until the opening in said blade is opposite the screw 7. The machine is then ready to wind a new cop.

Where the machine is small and particularly adapted for a class of work in which one operator must attend a number of spindles, it is preferable to mount several of these machines on one bed to be driven from and controlled by a single common gainer mechanism G. This single gainer mechanism is constructed and arranged to operate in con nection with a plurality of machines as follows: As shown in Figs. 4 and 5, at the top of the standards g and q is a shaft 10, supported in the bearings 11 and 11 Attached to this shaft and adjacent one end of the bearing 11 is the driving-pulley p, and at the opposite end of the bearing is the gear m, meshing with a gear n, carried on and rotating the shaft N, said shaft having a bearing 8 in the standard 9. At one end of the shaft 10 and adjacent the driving-pulley p is the expansible pulley L, described in my applications Serial Nos. 20,239 and 20,454. (Shown in detail in Fig. 8.) The hub of the pulley consists of two disks 150 151, threaded and adjustable to and from each other on a threaded sleeve 152, secured to the shaft 10 and fiXed in place after adjustment by a binding-nut 153 and clamp-screws 154. The periphery of the pulley is a ring 155, split transversely and with inner beveled faces adapted to correspondingly-beveled peripheries of the disks 150 151, so that by bringing the latter together or separating them the ring is expanded or contracted to Vary the diameter of thepulley. The parts of the sleeve on which the two disks are mounted are reversely threaded, so that by turning the two disks (connected by cross-pieces 156) in the same direction they are separated or brought together. The cam driving shaft U protrudes beyond its bearing 20 and carries in a swinging frame g, adjacent thereto, the gear 22, which in turn meshes with a pinion 23, Figs. 4, 6,and 7, attached to a shaft 0, which rotates in a suitable bearing in the swinging frame g. The shaft 0 carries at the opposite end a pulley L, driven from the expansible pulley L by a belt Z. The latter is maintained tight to prevent slipping by means of the weight Y, hung from the free end of the swinging frame g. Byincreasing or decreasing the diameter of the expansible pulley L the speed ratio of the shafts N and U and their connected devices may be varied as desired. The two shafts N and Uare supported in bearings in the standards g and y there being a sufficient number of the latter dependent on the length of the bed and of the shafts to be supported and are connected to drive the shafts 9 and the cam-shafts 25, respectively, by means of bevel-gears 14 and 14, each gear serving to operate the corresponding mechanism of two machines arranged in line with each other, as shown in Figs. 4 and 5, the gear 14 driving two opposite windingspindles through the clutchgears 12 and the gear l4 driving two oppo site cam-shafts through the clutch-gears 12. The rear end of each shaft 9 is reduced in diameter to form a shoulder, against which bears the washer 18, Fig. 2. Adjacent to this I Fig. 9, to swing them either into or out of enwasher is the bevel-gear 12, turning freely on the shaft 9 and held in place by the head of screw 19 in end of said spindle. The bevelgear12hasaninternalannular beveled clutchseat adapted to receive and engage with the periphery of a friction-clutch 13 to drive the shaft 9. The clutch and winding-spindle are connected to rotate together by means of usual keys or splines, allowing the clutch to slide freely to be thrown into engagement with the clutch-gear 12 to drive the shaft and winding-spindle or to be withdrawn when the motion of the latter is to be arrested. Any desired number or arrangement of splines may be employed; but I prefer to use a plurality of them, as indicated in Figs. 12 and 13. The splines 16 in this case are made integral with the clutch and are fitted to appropriate grooves or keyways in the windingshaft 9. Adjacent the end of the spindle-bearing J, Fig. 2, and fast on the spindle is a collar T, which, together with the collar 53 on the front en d, holds the spindle in place. Bearing against collar 0" is the saucer-shaped spring 15, which forces the clutch-disk 13 into engagement with the clutch-gear 12. The gearing and clutch connections on the camshaft 25 are identical in operation and, with one exception, in structure with thosejust described. The cam-shat't 25 is held in place solely by the cam D, clamped thereto and whose hub ext-ends between the two bearings V and 1V, thus preventing end play. To provide for the thrust ofthe spring 15 of the cam-shaft, a thin washer s is interposed between said spring and a second shoulder on cam-shaft 25.

When for any reason the winding must be arrested, it is essential that both the wind lug-spindle and the cam shall stop at the same time. To this end there aretwo levers T and T, Figs. 2 and 9, which are adapted to withdraw the clutches from engagement with their corresponding gears; The devices for disengaging the clutches from the gears are as follows: On each clutch is a disk portion oppositely beveled at its outer edge to make the latter of substantially triangular section. Adjacent the triangular edge is the extremity t or t of the lever T or T, in which there is an angular opening with sides made to match those of the rim of edge 13. This angular opening in the lever T or T is not directly opposed to said rim, but is so related thereto that when the lever T or T is rocked to engage the clutch the extremity t or t forces the clutch from connection with its gear bythe wedgingaction of the engaging surfaces. The levers T and T serve also as brakes to overcome the momentum of the rotating parts and insure their stopping promptly. These levers are operated from the rocker-shaft 31 at the top of the machine through the arm 33 and the roll 34, carried at its extremity. This roll is supported to move between the forked extremities 1G1 162 of the two levers T T,

gagement with their corresponding clutches. The roll 34 fits loosely on its pin on the arm 33, so that when forced in one direction it acts with substantially equal pressure on both levers to Withdraw the clutches from their gears. When forced in the opposite direction, the levers are rocked positively away from the clutches, leaving the latter to operate under the influence of the springs 15 and 15 to engage the clutch-gears. The lever T is provided with an arm 35, which when the said leveris forced from the clutch limits its movement by contact with the lever T and prevents it from so falling as to be placed beyond the line of action of the roll 34. The shaft 31 rocks in bearings at the top of frame A, and the spring 32, Fig. 2, acts to turn it in the direction of the arrowj, Figs. 1 and 9, to cause the stopping devices above described to arrest the winding. 7 Provision for adjusting the tension of the spring 32 is made in the adjacent collars 36 and 37, whose opposing faces have clutch-teeth so formed, Figs. 10 and 11, that the collar 37 is free to rotate on the shaft 31 in but one direction. The collar 36 is fastened to the shaft 31 and in such relation to the spring 32 that the latter forces the collar 37 against it and the clutch teeth into engagement. The spring 32 is connected with the collar 37 at one end and held from turning by 2. lug uon frame A at the other end. Radial holes are provided in the collar 37 to admit the insertion ofa suitable implement to turn said collar to increase the torsional force of the spring.

Near the opposite end of the shaft 31 from the arm 33 and adjacent the frame of the machine is the lever E, with which the operator starts the winding. When in the forward position, (indicated by thefull lines in Fig. 1,) the detent 46 at the extremity of the lateral projection 45 is engaged, with a corresponding detent 43 on the lever E. At such a time the levers T and T are withdrawn from engagement withthe respective clutches and the driving and winding mechanisms are operatively connected, To stop the winding, the operator presses the lever E to the right, Fig. 1, disengaging the detent-s 43 and 46 and permitting the spring 32 to turn the rockershaft 31 and act .upon the stopping mechanism to arrest the winding. The lever E is supported on the cam-shaft bushing V, Fig. 2, adjacent the hub fof the traverse-frame F, which carries the traversing thread-guide, and both are restrained from end play by the collar 26, clamped to the outer end of the bushing V. The lever E is pressed toward.

the winding-spindle by a spring 41, dotted lines, Fig. 1, held in sockets, one in the tension-bracket A and the other in the under edge of the lever E. To properly gage the amount by which the two detents 43 and 46 shall interlock, a set-screw 47, carried by the bracketjA, bears on a lug 166 of the lever E.

The shaft 9 carries a collar 53, Figs. 1, 2,

IIO

and 29, and on the lever E is pivoted a lever 51, having aweighted upper arm, with a projection 51*, and at the lower end of the opposite arm a pin 56, on which bears the thread during winding, so that its tension sustains the upper arm of the lever 51 and withholds the projection 51 from contact with the collar 53. The face of the projection 51 is not concentric with the pin or stud 51 on which the lever 51 swings, but has a slight pitch, forming a rotatable wedge, so that when said face makes contactwith the collar 53 the friction between the two members causes the upper arm of the lever 51 to be drawn downward, thereby wedging or forcing the lever E back from engagement with the lever E and causing the winding to be stopped. As oil and lint tend to gather on the collar 53 and neutralize the friction between it and the projection 51, one or more flats 53 are formed on said collar, causing the latter to positively engage the lever 51.

The tension devices are carried in the bracket A, attached to the frame A of the machine, and are caused to act by appropriate means. Those indicated, Fig. 1, comprise a hook y on the lower arm F of the traverse-frame F, through which a cord is passed, connecting the movable tension memher a with a rod 5, on which any desired numberof weights to maybe placed. To mechanically open the tensions, the movable tension member 0 has an arm (1, either attached or made integral therewith, as shown in Figs. 1 and 3, which when the tension is mounted on its bracket Aextends toward the main frame A. The lever 51 is extended beyond the pin 56 to engage with the arm (1 when rocked in the direction of the arrow 6, Fig. 1. To rock the lever 51 in this desired direction, a pin 0, Fig. 3, in the projection 45 of the lever E engages with a lug 51 on the upper arm of the lever 51. When lever E is in the forward position, (indicated 'by full lines in Fig. 1,) the upper arm of the lever 51 is free to engage the collar 53 to disengage detents 4:3 and 46; but when said detents are disengaged the movement of the lever E (actuated byspring 32 on rod 31, Fig. 2) brings the pin 0 against the lug 51, and thus carries the upper arm of lever 51 upward, thereby rocking the lower extremity against the arm q to open the tensions. hen the lever E is turned to start the winding, the lower extremity of the lever 51 is carried by the weight of the upper extremity away from the rod q, leaving the tension 0 free to respond to the action of weights to.

The traverse-guide employed in this machine must be made very narrow in order to wind the adjoining cop sections close together and also to wind close to the base of bobbins that are frequently used with 100111- shuttles. Further, itmust be so formed that when bearing on the barrel of the bobbin neither the base of the latter nor the cop-section next adjoining it shall interfere with the body of the guide or with adjoining parts. Again, as speed is a prime essential in machines of this type the guide must be as light as possible. To this end I make the upper portion of the guide thin and narrow, curved outward in substantially the form of a bow and far enough to permit the convex side of the guide to rest on the barrel of the bobbin without the interference mentioned. At the point where the guide bears on the bobbin or on the cop is an eye :20 with a lateral opening through which the thread is introduced. The bottom or body portion of the guide is substantially dovetail in cross-section to fit the corresponding socket in the traverse-bar.
